Weigela plant named  &#39;VUKOZGEMINI&#39;

ABSTRACT

A new and distinct  Weigela  cultivar named ‘VUKOZGEMINI’ is disclosed, characterized by large white flowers which change to pink. Plants bloom profusely and exhibit re-blooming. Plants have a low growth habit. The new variety is a  Weigela , normally produced as an outdoor garden plant.

Latin name of the genus and species: Weigela hybrida.

Variety denomination: ‘VUKOZGEMINI’.

BACKGROUND OF THE INVENTION

The new Weigela cultivar is a product of a planned breeding program conducted by the inventor, Vojtech Benetka in Pruhonice, Czech Republic. The objective of the breeding program was to produce new Weigela varieties with a low growth habit. The cross resulting in this new variety was made in 2004.

The seed parent is Weigela ‘Musca’, unpatented. The pollen parent is an unpatented, proprietary Weigela referred to as ‘99-19-254’. The new variety was identified as a potentially interesting selection in 2007, at a research nursery in Pruhonice, Czech Republic.

Asexual reproduction of the new cultivar ‘VUKOZGEMINI’ by softwood cuttings was first performed in 2007, at a research nursery in Pruhonice, Czech Republic. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in at least five successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘VUKOZGEMINI’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘VUKOZGEMINI’ These characteristics in combination distinguish ‘VUKOZGEMINI’ as a new and distinct Weigela cultivar:

-   -   1. White flowers that change to pink.     -   2. Large flowers with profuse blooming.     -   3. Re-blooming of flowers.     -   4. Low growth habit.

PARENT COMPARISON

Plants of the new cultivar ‘VUKOZGEMINI’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘VUKOZGEMINI’ differ in the following;

-   -   1. New cultivar has white flowers which change to pink, whereas         the parent has true pink flowers.

Plants of the new cultivar ‘VUKOZGEMINI’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of the new cultivar ‘VUKOZGEMINI’ differ in the following;

-   -   1. New cultivar has white flowers which change to pink, whereas         the parent has true white flowers.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘VUKOZGEMINI’ can be compared to the patented commercial variety Weigela ‘Bokrasopea’ (U.S. Plant Pat. No. 24,585). These varieties are similar in most horticultural characteristics; however ‘VUKOZGEMINI’ differs in the following:

-   -   1. New cultivar has larger flowers than this commercial variety.     -   2. New cultivar re-blooms less than this commercial variety.     -   3. New cultivar has flowers that open to the color white which         fade to strong pink, whereas the commercial variety has its         flowers open to the color white which fade only slightly to         pink.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘VUKOZGEMINI’ grown in a 1 gallon container.

FIG. 2 illustrates a top view of the same plant. Age of the plant photographed is approximately 2 years.

FIG. 3 illustrates a close up view of both white flowers and more mature flowers which have turned pink. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
